Where do Japan’s deficit and debt come from?

The most indebted and oldest country of the developed world: public revenue and spending since 2005, and thirty years of deficits since the end of the bubble.

Scope: Japanese general government (central government, local government, social security), national accounts, calendar years, OECD (2005 →) and IMF (1980 →) data. · Data as of Oct 27, 2026.

Key takeaways

  • In 2024, Japanese general government spent ¥246tn (38.7% of GDP) against ¥235tn of revenue (37.1%): a deficit of ¥10.6tn, or 1.7% of GDP. Gross debt stands at 218% of GDP, but the State also holds large assets: its debt net of financial assets is 84% of GDP.
  • The debt was built over thirty years of deficits: 63% of GDP in 1990, 236% in 2019 and a peak of 258% in 2020 (IMF). After the bubble burst in the early 1990s the public balance stayed in the red, with troughs at −9% of GDP in 2010 and 2020.
  • Ageing is the fastest in the developed world: people aged 65+ went from 20.3% to 29.8% of the population between 2005 and 2024. Over the same period health gained +1.6 points of GDP, family, housing and exclusion +1.5, pensions +1.3.
  • But Japan raised its taxes: the consumption tax went from 5% to 8% in 2014, then to 10% in 2019, and now brings in 4.9% of GDP against 2.4% in 2005; social contributions rose from 9.9% to 13.1%. Revenue grew faster than spending (+6.7 points against +4.0), so the deficit shrank from −4.4% to −1.7% of GDP since 2005.
  • Interest stays low despite the debt: 1.5% of GDP in 2024, against 2.2% in 2005, thanks to rates kept near zero by the Bank of Japan. Rising rates are the main risk. Social security runs a surplus (+1.2% of GDP); the central government carries the deficit (−3.0%).

Revenue and spending, year by year

For each year: left bar = revenue (grey), right bar = spending (colours), stacked by type. The gap between the two bars is the deficit. Tap an item in the legend to isolate it. Amounts in trillions of yen. Japan does not publish household and corporate income taxes separately.

What widened (or narrowed) the deficit

Change of each item in points of GDP between two years. Spending that rises, or revenue that falls, widens the deficit (bar to the left); revenue that rises narrows it (bar to the right).
